To all whom 2 2 may concern:

Be it known that I, JOHN F. PAOKER, residing at Chicago, in the county of Cook and State of Illinois, and a citizen of the United States, have invented a new and useful Im' proveinent in SeedingMachines, of which the following is a full description, reference being had to the accompanying drawings. in which- Figure 1 is a top or plan View; Fig. 2, a Vertical section; Fig. 3, a top or plan view, enlarged, of the dropping-plate; Fig. 4, a detail, in section, of the cut-off, droppingplatc, and dropping-tube; Fig. 5, a top or plan "iew enlarged, showing the cut-offs in place; Fig. 6, adetail in section on line at to of Fig. 5; Fig. '7, a detail showing the cut-offs; Fig. 8, a detail showing the supporting ring or plate and the manner of holding the cut'offs in place; Fig. 9, a detailof the supporting ring or plate with the cutoffs removed; Fig. 10, a detail of the supporting ring or plate, showing the spring for operating the cut-off; Fig. 11, a detail showing the block for the cut-offs.

This invention relates to that class of seedinginachines in which a revolving seed-cup plate passes beneath cut-offs for the seed in the cup to drop through the dropping-tube, and has for its object to improve the construction and operation of the cut-offs; and its na: ture consists in providing a spring located between and acting on the heels of the cut-offs and in pivoting the cutoffs in a plane directly in line with the lower face of the cut-off, and in providing the receiving cut-off with an un der cavity for the reception of a kernel,to allow the cut-off to drop to place even ifa kernel inore than required for filling the cup passes beneath the cut-off, and in the several parts and combinations of parts hereinafter described, and pointed out in the claims as new.

In the drawings, A represents a circular ring or lllll of a diameter for the size of dropper desired. This ring near its outer periph err is provided, as shown, with a vertical flange, a, for securing the hopper in position, and has a central circular opening corresponding in diameter to the diameter of the seedcup plate, into which opening is projected a housing formed of an upper plate, A, and a side plate, A, having a circular shape corresponding to the shape of the central opening, as shown in Figs. 5 and 6, leaving the ends ofthe housing open and clear for the reception of the dogs or cut-offs, and, as shown, the housing at one end is longer than at the other to form a guide for the cut-off or dog beneath which the seed-cups pass-to drop the seed, and this wall A also forms a guard against the entrance of the seed beneath the housing except as it is carried thereunder in the seed-cups.

B is a platelocated on the under side of the ring or rim A, in line with the top plate, A, of the housing, and projecting beyond the edge of the rim or plate, and having on its projected end ears or side projections, b, and,

' as shown, the under face of the ring or arm A is provided with a recess, b to receive the plate 13, and the plate is secured in position by a screw, 1).

O 0' represent the cutoffs, one of which, 0, is provided on its under face with a recess, 0, of sufficient depth to receive a kernel of corn, and this [cut-off 0 around the opening 0 is provided with a wall or shell, so that the opening will be entirely enclosed. The other cut-off or dog, 0, has its face cut away to leave an opening, 0 which opening extends across the dog from side to side and is not inclosed on its sides. The form of the cut-offs or dogs 0 C on their under face is shown in Figs. 7 and 8. Each dog or cutoff at its heel or rear end and on each side is provided with a trunnion, c, which trunnion is located to have its bottom in the same plane as the plane of the lower face of the dog or cut-off, and the edge of the under face of the ring or rim A and of the under face of the wall A are provided with openings a and a, respectively, to receive the trunnions c and give the dogs or cut-offs a pivotal hearing, as shown in Fig. 8. The cut-offs are of circular shape on the sides to correspond to the shape of the ring or rim A and the wall A. The under face of each dog or cut-elf at its rear or heel end is provided with a recess, 0, into which projects the ends b of the plate 13, and by which the out-offs are held from dropping down or becoming displaced in use.

D is a coiled spring located beneath the housing-plate A and between the heels of the dogs or cut-offs, as shown in Fig. 10, one end of the spring receiving a pin, d, on the end of the cut-off O, and the other end of the spring receiving a corresponding pin, d, on the end of the cut-off G, the pins at being located in the same horizontal plane and being of sufficient length to receive and support the end of the spring, and the spring is maintained against side movement by being located in the cavity A formed by the edge of the ring or rim A, the inner face of the wall A, the top plate, A, and the under plate, B, as shown in Fig. 6. The pins d are located near the upper face of the dogs, so that the spring, bearing on the rear end or heel of the dog around the pins, in connection with the trunnions located in the lower plane of the dogs, will act to throw and hold the forward end of the dogs down, and this location of the spring and the pivotal points of the dogs is sufficiently tangential to have the spring act quickly, and at the same time the location of the pivotal point for the dogs and the bearing-points for the spring is one by which the spring is not compressed to its full extent in the operation of the cut-offs or dogs.

E is the seed-cup plate, having, as shown, three holes, c, which form the cells, but which may he provided with a greater or less number of holes, according to the nulner of cells required for the distance apart in dropping. This plate at its center is provided with a round hole to receive a stud, by which it is held in position, and on its periphery is proi'ided with points to enter recesses g in the driving-ring.

F is the stationary dropping-plate,having a holc,f, which communicates with the interior of the dropping-tube F, which tube at its upper end is riveted or otherwise secured to the under face of the plate F. This holef is located in the circle described by the hole 0 as the plate E is revolved, so that the seed in 6 can enter the holefand pass down the tube F.

G is the carrying-ring, having its exterior under face provided with cogs or leaves which mesh with the cogs or leaves of a wheel, G, by the rotation of which wheel the ring G is revolved, and this ring, being connected by the points and recesses g with the plate E, revolves such plate; and, as shown, the plate F has a central stud which enters the opening in the plate E and around which the plate rotates.

H is a shaft mounted in suitable bearings, H, on a frame or support, and on which the wheel G is securely mounted.

I is a sprocketwheel on one end of theshaft H and over which a chain passes to drive the wheel and shaft as the machine on which the dropper is mounted is moved forward.

J represents legs forming a frame or support on which the several parts of the seeding-machine are mounted, the legs coming to a common center at their upper end and forming a tube, J, to which is secured the stationary plate F by means of a bolt, h, and, as

shown, a washer, J, is interposed between the plate F and table J which washer may be omitted if desired. The bearings H for the shaft H are formed in cross'bars running from leg to leg J, and. as shown, the table J is provided with side projecting ears, j, which,

when the parts are together, coincide with side projecting ears,-vl, on the plate A, and through which ears t j bolts are passed to attach the plate A to the frame.

K is a receptacle made of sheet metal or other suitable material and riveted or otherwise secured at its lower end to the flange aof the ring or plate A, and, as shown, the upper end of this receptacle is closed by a cover, K.

The dogs or cutoffs O O, with the spring D between them, are dropped into the housing with their trunnions resting in the openings or bearings c a formed in the ring A and wall A. The plate B is then placed in position with the points I) in the recesses c in the heels of the dogs 0 O, and there secured by the screw 1), and when together the tendency of the spring acting on the upper end of the heels of the dogs tends to throw their forward points down, and thelimitof downward movement is controlled by the ends I; abutting against the end wall of the recesses, and this limit of downward movement is sufficient to keep the spring under a strain that will tend to hold the forward ends of the pawls effectually down onto the under face of the plate E when the parts are together. The plate F is attached firmly to the table J by the bolt h. The plate E is dropped on top of the plate F with the stud on F in the opening in E. The ring G is dropped around the plate E with the points 5 in the recesses g, the ring meshing with the wheel G, mounted on the shaft H,

and the wheel I :is affixed to the shaft H, the shaft being mounted in its bearings H. The receptacle K, attached to the ring A, with the ring, is then secured in position by cars t'j, and when in position the dogs or pawls' will lie so as to cover the holes in the plate E as such plate is passed beneath them when rotated.

In operation the wheel I is driven by the chain or other driving device from some moving part of the machine to which the dropper is attached, rotating the shaft H and wheel G, and this wheel G rotates the ring G, and through the connection thereof with the plate E rotates such plates, causing the holes 6 to pass successively, when filled with seed, beneath the cut-off, the forward cut-off acting to allow only the seed in the cup to pass beneath it, and as the seed in the cup passes beneath the cut-off it drops through the hole f into the seed-tube F and passes to the ground. As shown, the legs J are provided with feet having openings through which bolts can be passed to attach the dropper to the machine with which it is to be used.

The tendency of the spring D is to throw the forward ends of the cut-offs down, so that such ends will bear firmly 011 the upper face of the plate E, insuring a cut-off of all grain except that contained in the hole 6, which is passing beneath the forward cut-oft or dog, as a general rule; but in case the cut-off should beheld up by the grain, so that its forward end would not be thrown down by the action of the spring as the plate E is revolved, the grain holding up the cut-off will pass beneath the cut-off and will not interfere with the action thereof or hold the cut-off up, the cavity in'the under face of the dog or cut-oil allows the grain to pass therein, so that the spring can act and throw the forward end of the dog onto the plate E, and the kernel thus caught will be dropped as the next succeeding hole passes beneath the cutoff, and by locating the spring D between the rear ends or heels of the cut-offs but one spring is required to operate both out offs, and this spring being located at the upper end of the heels and above the plane of the trunnions of the cut-off will not be compressed toits full extent in the operation of the cut-off, causing the spring to last longer without losing its reactive force.

The hole f in the plate F is located immediately under the cutoff dog 0, with its pe riphery in line with the inner face of the end wall of the cutoff, by which means the seed will drop as soon as it enters the opening 0" on the under side of the dog, or even while the dog yet rests on it, thereby having the pressure of the dog to force the kernel out of the dropper-plate and into the tube F, and in case the seed passes the opening at first the. rear end wall of the dog 0 will act and force the seed back to enter the holef, forcing the seed through the hole a. The location of the hole f and its relation to the end walls of the cut-off C with the cut-out portion on the under face of the cut-off, causes the cut-off to art and force the seed through the hole 6, thus obtaining all advantages of a forced feed by dropping the grain while the pressure of the dog is yet on the kernel, as most kernels are as thick, if not more so, than the dropperplate used in this planter.

WVhatl claim as new, and desire to secureby Letters Patent, is-

1. A spring, D, located and operating between the heels of the cut-offs or dogs, substantially as specified.

2. A cut-off, 0, having its under face provided with a recess, 0, for the reception of grain, said recess being deepest near the outer end of the cut-off, and contracted in depth toward its inner end, as shown, for the purposes described.
